Always Connected PCs offer always-on connectivity and long battery life. These ultraportable devices are thin and light enabling you to open, connect and work anywhere. Always Connected PCs are powered by Arm processors like those found in your smartphone or tablet.

You can benchmark the battery life of Always Connected PCs with the PCMark 10 Applications, Video and Idle battery life scenarios to create a Battery Life Profile for the device. 

The Modern Office and Gaming battery life scenarios are not compatible with devices powered by Windows 10 on Arm. You can force these tests to run on Arm-powered devices from the command line. but as the workloads are not optimized for Arm devices, the results should not be taken as representative of the battery life capabilities of these devices.
